Yes agreed. Some countries and cities had better taxi service than others. But one of beauties of early day Uber was that I was able to use the same app globally (in the US, Taiwan, and even Chiba) and it used my prexisting saved credit cards even! No fumbling for the local currency, registering a local payment method, or worrying if I am going to be scammed by the driver—just a consistent note global taxi hailing experience.
